7 Hidden Eco-gems: Under-the-Radar Cities Worth a Visit

Scenes from MalmÃ¶, Sweden -- a hidden green city gem -- BjÃ¶rn SÃ¶derqvist @ flickr.Portland, San Francisco, and New York. These three cities consistently rise to the top of U.S. and even global lists of great green cities. And while these cities, through both some natural advantages and hard policy work, have earned their green cred, there's more out there taking sustainable city building seriously. Caveat: This is not a scientific list, nor is it a ranking. Instead, it's a list of current cities (thus we skip over the not-yet-real places such as Masdar, Tianjin, and Dongtan) that meet most criteria of effective green cities and are worth a look for both right now and future greening.

After that, the other important factors seem to be:

Good streets for bike and pedestrian traffic

Robust transit

Lots of green canopy

Expanding and connecting of open spaces

Natural storm water management techniques

Renewable energy for metropolitan power generation

But which cities out there are the up-and-comers, those starting to embrace these criteria, with the aesthetics and spirited citizenry that make cities great -- and green?

2. Toronto, Ontario, Canada

Generally when people think "green city" and "Canada" it is Vancouver that comes to mind, and for lots of great reasons, including 90 percent of its energy generated by renewable sources. But Toronto garnered top marks in Ethisphere's recent evaluation of cities that would be able to call themselves "Global Sustainability Centers" by 2020. Toronto can't perhaps generate as much excitement as Vancouver, but it scores well on the basics, has a good plan in place and some impressive stats —- the city has reduced greenhouse gas emissions 40% since 1990. Great ideas in Toronto include the adoption of a green roof policy, the green makeoverat the Brickworks, and zerofootprint toronto, which has the potential to inspire CO2 footprint makeovers and change the city's green self-image!
